/*
I'd like to report a false positive, and the wiki sent me here to get an
account.
This constructor: RunOnceTask(string_view name, function<void()> && fn);
Results in: Class 'RunOnceTask' has a constructor with 1 argument that is not
explicit. A complete cpp containing this can be found at:

Thanks.
